Is it possible to go back to Camera RAW after some editing in PS CS6?

[Dulce]

Hello, Is it possible to go back to Camera RAW after some editing in PS CS6, maybe to edit exposure a little more? I remember seeing that is possible, I know it is possible in CC but not sure with CS6, maybe it was a dream I had

thanks

No, it's not possible in CS6 or any other version. "Camera raw filter" in PS is not the same thing as working on a raw file. This is the method that Damien recommends in situations when you need to replace the raw edit: http://www.damiensymonds.net/2013/10/replacing-raw-edit-in-psd.html
